Plan On Cheating On A Drug Test For Weed? Think Again, It’s Not Worth It.


There are three primary ways to “try” to cheat a drug Test: Dilution, Substitution, and Adulteration.

How to cheat on a drug test for weed is a very common question and is googled over 10,000 times a day. Marijuana is more popular than ever and employers are also drug testing for marijuana more than ever. Millions of people each year need help passing a drug test for all kinds of different drugs, the most common being marijuana. Many people think the only way to pass a drug test is to cheat by using fake urine or sketchy cover-up products and drinks. We urge all our readers who need help passing a drug test to read this article and realize that you can pass a drug test for weed naturally without cheating by fully detoxing your body.

How can a testing lab tell I cheated on my drug test for weed?

At the Laboratory:

Labs have greatly improved their methods in detecting those specimens that have been tampered with by the donor.

Cheating on drug tests by “adulterating” urine samples, or altering a specimen by changing its concentration, is a common practice that marijuana users use to hide the presence of THC in their system. Previously, some abusers were able to pass a drug test by using one of these strategies. But new lab technologies are now detecting drugs in samples that were altered and un-testable before. Today, lab tests measuring specific gravity, pH, creatinine levels, and temperature are determining “positive” and “negative” results – and attempts at cheating drug tests – more accurately than ever.

Lab tests today can often indicate that the sample is not from the donor. In a somewhat humorous case, a man substituted his sample with that of his wife. When the specimen failed the temperature test, subsequent lab testing indicated “he” was pregnant.

Adulterated samples will throw pH levels off or exhibit substances not normally found in urine. In cases where a definite positive or negative result cannot be determined, donors may be required to resubmit a sample under “direct observation” supervision. New lab testing methods now easily determine the presence of nitrites, such as the masking agents found in many products sold online and head shops.Once nitrites are detected, further testing removes the masking effect to discover which drugs are present. Laboratories are constantly updating testing methods as new adulterant products enter the market.

At the Collection Site:

While lab technology can now identify adulterated samples and other attempts at cheating drug tests, safeguards also exist at the urine specimen collection site, whether it’s at a clinic or at the job-site.

Onsite specimen collections are the most effective way to catch would-be cheaters. Cheating drug tests has caused more and more companies to have a trained Drug Test Technician (DTT) visit their offices, warehouse, manufacturing plant, or other sites “onsite” and have the drug test urine specimen collections performed right there, where their employees are “on the job”. A DTT considers a properly-performed drug test collection their top priority. This includes taking the special precautions necessary to ensure that the donor (employee) is not attempting to either substitute or adulterate their specimen.

In the case of “onsite” collections, the donor is routinely required to report immediately and directly to the Drug Test Technician (DTT) when notified of drug test. The donor is not permitted to “go the the locker room”, “run down the hall”, or “get something out of the car” (often-used ploys to enable a cheater to retrieve adulterants or substitutes) before seeing the DTT and providing their specimen.

Getting Caught Cheating On A Drug Test:

Under U.S. Department of Transportation (USDOT aka, “DOT) regulations, DOT- employees whose sample is determined to be tampered with are automatically reported as “positive” on their drug test and they must be immediately removed from their positions by their employer. Non-DOT employees are not subject to the same regulation, however, may still be released from their duties depending on the employer’s company drug policy.

This year, approximately 2,800,000 drug tests results will come back from the labs reported as “positive” for one or more drugs. A greater percentage of those this year than last year will be from cheaters who tried to “pass” and were not successful. Attempted cheaters will be caught during the specimen collection process or they will be discovered by the lab. As specimen collection procedures and lab analysis technology improves, it will be an even a greater percentage who are caught trying to beat a drug test next year and the next.

Bottom line: If it really is that important to you to get that job or keep that job, their is only two 100% effective ways to pass a drug test, simply: to be entirely drug-free or to fully detox the body naturally.

Removing marijuana from your system naturally is the only reasonable, honest, legal solution. We hope the information above has helped you understand why cheating on a drug test is a terrible idea and how difficult it has become recently to trick the system. We strongly urge you not to buy detox products from a head shop or shady online business with no accreditation. Don’t waste your time, money, job or freedom on unproven drug cleansing products.

  1. Hot pregnant wife on

    Im sharing because the comments ive read here and elsewhere saved us. We are married, my husband was laid off in August 2015, we have a baby and I am due in 2 months. Our unemployment ran out this week

    My husband had to pass a dt yesterday. He was a daily smoker he slowed down 3 months ago to a couple times a week and then quit two weeks prior to getting the offer. We had 10 days. He tried a hardcore ALL FIBER diet, WITH SUPPLIMENTS. Ddetox tea and drinks, so much water and 5 times a day in our sauna. After five days he was still positive, even if he tested negative, we were concerned. So we had to replan for substitution. Though he kept the detox going. On the day of the test he still tested positive with a light control liine. No bueno.

    it was a basic ecup test, not dot.

    He substituted clean urine. I wouldn’t rely on detox.

    How we substituted. I got clean male pee the night before in a glass jar, though I’ve heard it’s illeagal to test hormones, I’m still pregnant and didn’t want to take a chance. Refrigerated overnight.

    I bought a 3oz lotion tube at walmart, handwarmers and a temperature strip online, rubberbands, and a baby bottle warmer for the car (kept the receipt and returned it.. said it broke). We brought two thermometers to confirm the temperature. He wore a pair of my spandex shorts to be sure it wouldn’t go anywhere.

    The baby bottle warmer got the temp up to 106, so be aware. It gets hot. The temp should ideally be between 94 and 100 but you can pass 90 to 100.

    It was an hour door to door.

    We had to sit let it cool down in the parking lot next door. Checked with both thermometers until it was a hundred. Rubber banded the hand warmer to the pee, wrapped it in papertowel, and sent I’m in.

    They handed him an ecup, he went in a private bathroom and (having practiced) was able to quietly open the lotion bottle and empty the cotents. Checked the temp strip, swirled it a bit to cool down, peed for real and handed the sample.

    The woman looked at it, nodded and he left.

    He passed. Has a brand new job.

    Originally he was going to use a Scrunchie to strap it on, but we didn’t think he would be observed.

    I recommend wearing a belt that makes a little noise and jiggle it if you need to cover up the sound of opening the top. If your eine observed, don’t close it, it makes a snap sound. Use the papertowel to prevent dripping.

    Having someone with you does a lot to keep you calm and help you measure temps. You can do it on your on though. We were sick with worry but it went very smoothly because we practiced alot and ironed out all the problems.

    Practice in the car with the warmer, heating up and cooling down. Practice opening and closing quietly. Practice walking around with it in your pants, that’s how we knew boxer briefs were not enough. We had a lot of trial and error. Just wanted to share a passed test in 2016.

  2. I’m a very light smoker. Maybe 2-3 hits off a bowl at night. I recently lost my job and need to test. How long before it gets out of my system?

  3. I’ve been using a home test kit. The kit shows a real faint line in the negative. Does this mean I will pass the test?

  4. I’m a female who weighs 120 and I’m 5’6.I was a heavy smoker for about 3 months smoking every day. I quit exactly a week ago. I had applied for a job they had me come in to fill out paperwork bc I got the job. They hit me with a mouth swab that I had to hold in my mouth for5 mins. I made sure I put barley any saliva in it. Before my mouth swab I had drank three bottles of water. Do you think that it will be positive for THC?I’m freaking out

  5. Spectrum labs .yourinluck. c o m is what u want been using them for a decade and they keep it fresh with the gravity, ph,creatine, urea… And others…

  6. You have to suck it up. Stop smoking weed or popping pills so you can pass the drug test. But here’s what could happen: My buddy Jesse was going to school and working nights as a security guard. He was an employee randomly selected for a drug test. He took it and passed, but by pure bad luck his name was selected again two days later. He passed both times because he doesn’t do drugs. In an addict’s situation this is a big problem. STAGE an accident immediately. Have a friend or someone call in that you fell off a latter at home. This way you can show the employer and drug testing center you were given pain medication. They’ll either postpone the test, or test for everything but the recent doctor prescribed medication.

  7. she took a swab test…those can only test for immediate consumption within 4 DAYS….so two weeks before a swab test…as long as you brush well…is more then enough time…..just saying

  8. I agree. This blog is ideal for those of us who support legalization and who personally know from experience there is no detrimental effect on your mental health. For me pot is medicine and is not a gateway drug leading to serious narcotic abuse. Helps with sex, and my nerves versus having to take an addictive anti-depressant like Prozac or Valium.

    In regard to sex, I don’t need it to maintain an erection like having to take Viagra, marijuana enables me to abstain from reaching climax too soon. I can literally last for a couple of hours, and between the oral sex and intercourse my wife typically has 8-10 orgasms–or more sometimes–before demanding that I finish as she’s totally worn out.

    Thank you, Weed Blog.

  9. It depends how often and how much you smoke to determine how long it’ll be in your system. If you smoke every day, it could stay in your system a lot longer than 2 weeks, or even 4 weeks. At my old job, I was allowed to take pain meds, and operate equipment and drive as long as I told them I was taking them. Didn’t make much sense to me but whatever. I don’t mean to rain on your parade but 2 weeks doesn’t seem like a long enough time but good luck. I hope they just legalize it everywhere!

  10. I would like to no if there is any way around losing my pain doc.they did a swab test and I smoked 2 weeks ago.will it show up?

  11. This is good info supplemented by a sales pitch. Detox is a healthy thing to do for many reasons… not just to pass a drug test and that info should be part of the sales pitch. No way I’m going to use anything illegal as I’m thankfully not suffering enough to justify it. I’m hoping for the legalization… and soon.

  12. I agree!! If I had to guess these negative comments are from other companies that don’t have the Weed Blog approval. Keep up the good work Weed Blog.

  13. Thanks for pointing it out. So here’s the deal:

    We get A LOT of questions about drug testing. Sometimes 50 questions/day. We admittedly don’t know much about this so we reached out to a couple companies in search of something a little more legit then our “pee in a condom” method.

    We were looking for someone willing to write informed articles and also commit to answering a “tip-line” email inbox for readers that might have questions. We think the people at Magic Detox are knowledgeable and they have what we believe to be solid product.. Part of the arrangement is they get some free advertising. If they made a bad product or there wasn’t some good information, we wouldn’t post it.

    We won’t work with any business or advertiser that we don’t believe in or doesn’t provide a benefit to our readers. No annoying ads for bootleg boner pills, worthless software, or fake headlines about googling your own name.

    As with everything you read, take it for what it is and always do your research. We just try to chip in when we can and to not suck while doing it.


    P.S. Thank you everyone for your input. We will take it all into consideration for future articles

  14. I have failed using methods to mask my marijuana use, therefore I will not go that route ever again. I at 50 years old have to go a minimum of fourteen days clean to pass a drug screen. Its called fasting and its good for self awareness and reality check. These companies don’t give a damn about anything except making money. As the articles says testing procedures are constantly being improved so to say.
    And I am disappointed that these ads have been supported by this blog

  15. It does not. I found the info helpful. Blogs are supported by ads. I Check this blog several times a week and love it!! So what if a few ads are in the article. It’s the world we live in now. I’ve seen 25 fan duel ads today.. So what..

  16. Jordan Shorette on

    its a visual aid that happens to be of an advertisement, so I fail to see where it degrades any credibility.

  17. the only winners in the war on drugs are the drug testing companies, one thing you didn’t bring up is a test that is “inconclusive” is the same as a positive

  18. Jordan Shorette on

    That’s exactly what I’ve done the minute they mention that I have to surrender bodily fluids I tell them sorry but your company discriminates and I refuse to work for a dishonest company. I’ve had to do it three times already but its there loss not mine. I always still seem to find work with better human beings.

  19. I agree. Theresa link right after the 1st paragraph. I stopped taking it seriously as soon I saw that. This is an AD, NOT an article!!!!!

  20. Re; the ad photo.
    Does she, or does she not, look like the Dermatologist that O D on cocaine in NYC.

  21. so i shouldn’t use anything from a “sketchy” headshop, but I should use these pills made by a company I’ve never heard of and are basically just as effective as a placebo? Is this an ad or an article? Can’t tell.

  22. stellarvoyager on

    How about simply refusing to work for — and do business with — companies that require ULA’s (Urinary Loyalty Oaths)? Stop trying to play their game, and let them have all of the “drug-free” slackers who show up hung over, call out sick because they’re hung over, etc.
